Wander around the ramshackle street of Nonbei Yokocho ('Drunkard's Alley’) where you'll find rows of tiny bars – some so small that they only fit four or five people at a time. The street once hosted the Tokyu railway corporation's head office, but things here changed drastically in the early postwar years. Dating back to the early 1950s, popular yakitori shops and similar eateries rule the alley. One of the most popular is Okasan ('mother'), a bare-bones joint that's been serving hungry patrons for three generations. You'll also find bars, bistros and quirky shops at Nonbei, conveniently located right by bustling Shibuya Station. Although it's become a tad more touristy in recent years, this one's still one of Tokyo's most representative yokocho.
